JOHN E. BOSSERM'AN', 0F MURRAY, IOWA.

GRAIN ELEVATO E.

Application filed February 20, 1923.

To all whom it may concern:

Be it known that I, J oHN E. BOSSERMAN, a citizen of the United States, and a resident of Murray, in the county of Clarke, State of Iowa, have invented acertain new and useful Grain Elevator, of whichthe following is a specification.

This invention relates to mechanism for conveying and discharging grain from the delivery spout of a grain elevator to the inside and ends of cars.

Heretofore it has been the practice to deliver the grain through the grain door of the car on the car floor and just inside of the door, and to shovel it back into the car by manual labor. On account of the amount of labor involved and the dust conditions it is almost impossible to get men to do this work.

It is, therefore, the object of my invention to provide a mechanism of simple, durable, inexpensive and light construction which may be easily and quickly attached to the upper edge of one, of the car doors, and

which will automatically deliver the grain from the delivery chute of the elvator to either end of the car.

More specifically it is the object of my invention to provide a conveying or delivering mechanism for the purpose above a stated, which may be constructed in sections and so arranged that the said sections may be easily assembled or taken apart so that the machine may be easily handled and moved from one car to another.

My invention consists in the construction, arrangementand combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed, outin my claims,

and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my im proved device showing the manner in which it is mounted on a grain door of a car.

V Figure 2 is a horizontal, sectional view taken through a car showing in elevation my improved mechanism and the manner in which it is mounted therein.

Figure 3 is an enlarged, detail, sectional View showing one of the pivoted members on which the conveyor is mounted.

Figure 1 is an end elevation of my improved device.

The numeral 10 indicates the sides and 11 the bottom of a grain car. The sides 10 Serial No. 620,12 1.

are provided with door openings 12, each of the openings 12 being provided with the usual grain doors 18. The grain doors 13 consist simply of a series of horizontally arranged boards nailed to the inner edge of the door frames 14. The boards of the grain, doors are nailed to the said door frames and usually extend about four feet high, the grain door being about eight feet high, which would leave the upper edge of the door 13 midway between the top and bottom edges of the door opening 12.

My improved device comprises a horizontally arranged platform or base 15 which is provided at each end with a bracket 16 having at one of its sides a hook 17 provided with a clamp screw 18. The hook and said screw form a clamp designed to be placed over the upper edge of the door 13 for securing the platform in a horizontal position, even with the upper edge of the door 13 and extending inwardly from said upper edge. The brackets 16 are preferably provided with braces 19 to hold the platform 15 against longitudinal movement.

Ro-tatively mounted on the platform is: a base member 20 pivoted to the platform by the pin 21. One end of the base is provided with upright suppori'iing brackets 22. The upper end of each of the brackets being provided with an outwardly inclined slot 23. The brackets 22 are spaced apart a short distance and designed to receive between them a conveyor box 24-. The said conveyor box has bearing members 25 extended laterally from each of its side members, said bearing members being designed to restin the slots of the members 23, as clearly shown in Figure 3. This provides means whereby the outer end ofthe conveyor box may be elevated or lowered and whereby the box may be easily and quickly detached by simply lifting it out of the inclined grooves.

The pivoted end of the conveyor box is provided with upwardly extending plates 26 which are designed to support a side plate 27 detachably connected thereto by means of bolts 28. The upper end of each of the plates 26 is provided with laterally extending pin 29. Each of the pins 29 is designed to receive a notched brace bar 30. lower end of each of the brace bars is pivoted to the base- 20 by brackets 31. The brace bars 30 are designed to support the free end of the conveyor box 2%, in a num- The thrown back ontop of theconveyor box 24. The outer end of the extension member .32 is provided with a shaft '34 designed to receive a pulley 35, while the bearings 25 are designed to receive a transversely arranged shaft 36 on which is supported a pulley 37.

v The pulleys and 37 are designed to carry a conveyor belt 38. The upper runof the said belt is designed to travel over a floor board 39 in the box member 24, and a floor board 40 in the extension32. The ad jacent ends of the boards 39 and 40 are cut away to form a notch 41 between them. The said notch is for the purpose of permitting the free end of the extension 32 to swing upwardly, while the belts are in position on the rollers, without stretching the said belt.

' One end of the shaft 36 is provided with a pulley wheel 42 designed to receive a belt 43 operated from an electric motor 44, the said motor being placed on the base 20 at V the opposite end from the'uprights 22,

Thus it will be seen that if the motor 44 is operated, the shaft 36 will be rotated through the belt 43 and the pulley 42. 1 This will cause the conveyor 38 to be rotated in an anti-clockwise direction, as shown in Figures 1 and 2 and any material which is delivered to the conveyor through a chute 45 will be carriedoutwardly'to the end of the conveyor 38 and discharged.

The platform 15 is placed on the upper edge of the door 13, as clearly shown in Figures 1 and 2 and the clamps 17 over the upper edge of the said door. It will be seen that the platform may he slid longitudinally along the upper edge of the door and a certain amount of adjustment made between the outer end of the conveyor and the end of the car.

It will further be seen that the free end of the conveyor may be swung laterally so that the material may be discharged midway between the sides of the car.

After one end of the car has been filled and it is desired tc till the other end, the operator simply swings the free end of the extension member 32 upwardly about the hinge 33, which will then permit the conveyor to swing about the pivot 21 and between the sides of the car until it has reached the position where it will be in alinement with the opposite end of the car.

The extension 32 may then be lowered and the side plate 2f7 adjusted to the opposite side of the conveyor and thechute replaced,

from the car, the extension 32 is thrown upwardly and inwardly to a position over the top of the conveyor 24, after which the braces 30 are unhooked from the pins 29 and the belt 43 removed, which will leave' the pivot end of the conveyor free to be disengaged from the supports 22 by lifting upwardly and inwardly. The conveyor 24 is removed through the car door opening, and

is comparatively light and may be easily handled by one man. The platform 15 may then be removed, which is also very light, due to the fact that a very small motor is required to operate the mechanism.

Thus it will be seen that I have provided a device of simple, durable and inexpensive construction which is ada ted to deliver grain or the like to the en s of in cars, and which may be easily and quic 1v placed in position for operation, or quickly and easilyvremoved by a single operator without the use of tools.
